Last week on The Real Housewives of Orange County, a new housewife joined the cast: toned and tanned Lynne Curtin, a sexy, stay-at-home mother of two teenage girls. Tamra Barney, Vicki Gunvalson and Jeana Keough have already been rattled over meeting blonde bombshell Gretchen Rossi, so tensions escalated even higher when they met newest housewife, Lynne.

On tonight's episode called “120 in the Shade,” Jeana, Vicki and Tamra assemble for a Fourth of July getaway, resulting in fierce personal fireworks. Meanwhile, Gretchen vacations in the mountains and receives news about her fiancé. And the newest housewife arranges a birthday celebration for her daughter.

Amidst the arrival of new cast members on The Real Housewives of Orange County, it seems that the show is on the verge of losing another of its original housewife. According to E! News, Vicki Gunvalson is apparently having second thoughts about remaining with the reality series if Bravo decides to continue the show beyond its currently-airing fourth season.

"No comment," Gunvalson told E! News when asked if she would be interested in participating in the fifth season of The Real Housewives of Orange County.

Additionally, Vicki's husband of 14 years, Don Gunvalson, regrets the couple's participation in the reality series “100 percent.” Evidently, part of Don's nuisance was caused by an episode in which Vicki laments that her “love tank is depleted” and uncertain of her husband “can fill it up.”

"He's a vice president of a company. He has to go to work the next day, and he has people saying, 'Wow your wife really trashed ya again last night,'" Gunvalson told E! News. "For a man, it's horrible. All I could say to him is, 'Honey, I love you. I'm sorry. Let's get past it.' And he was like, 'You should have thought about that when you were blabbing about your stupid love tank.'"

The Real Housewives of Orange County airs tonight at 10pm ET/PT on Bravo.
